None of the patches applied, so I assume they are upstream.

Tested locally. Please push if it's good.

To check if the patches are in the 2.6 release, I cloned the Git repo
and used `git describe --contains`. The patches helpfully include the
Git commit hash, so that commit can be passed to `git describe
--contains`.

So, for 'wpa-supplicant-CVE-2016-4477-pt4.patch':
$ git describe --contains 2a3f56502b52375c3bf113cf92adfa99bad6b488
hostap_2_6~513

So, we see that the commit is reachable from the 2.6 release tag, 513
commits in the past. I think it's a reasonable to assume that upstream
releases correspond to the Git tags.

I did that for all the patches. I don't think it's enough that the
patches don't apply; there could have been incompatible code changes
that prevent their application but did not fix the bugs.

Works for me, thanks!

-Subject: [PATCH 1/5] WPS: Reject a Credential with invalid passphrase
-
-WPA/WPA2-Personal passphrase is not allowed to include control
-characters. Reject a Credential received from a WPS Registrar both as
-STA (Credential) and AP (AP Settings) if the credential is for WPAPSK or
-WPA2PSK authentication type and includes an invalid passphrase.
-
-This fixes an issue where hostapd or wpa_supplicant could have updated
-the configuration file PSK/passphrase parameter with arbitrary data from
-an external device (Registrar) that may not be fully trusted. Should
-such data include a newline character, the resulting configuration file
-could become invalid and fail to be parsed.

-Subject: [PATCH 2/5] Reject psk parameter set with invalid passphrase
- character
-
-WPA/WPA2-Personal passphrase is not allowed to include control
-characters. Reject a passphrase configuration attempt if that passphrase
-includes an invalid passphrase.
-
-This fixes an issue where wpa_supplicant could have updated the
-configuration file psk parameter with arbitrary data from the control
-interface or D-Bus interface. While those interfaces are supposed to be
-accessible only for trusted users/applications, it may be possible that
-an untrusted user has access to a management software component that
-does not validate the passphrase value before passing it to
-wpa_supplicant.
-
-This could allow such an untrusted user to inject up to 63 characters of
-almost arbitrary data into the configuration file. Such configuration
-file could result in wpa_supplicant trying to load a library (e.g.,
-opensc_engine_path, pkcs11_engine_path, pkcs11_module_path,
-load_dynamic_eap) from user controlled location when starting again.
-This would allow code from that library to be executed under the
-wpa_supplicant process privileges.

-Subject: [PATCH 3/5] Remove newlines from wpa_supplicant config network
- output
-
-Spurious newlines output while writing the config file can corrupt the
-wpa_supplicant configuration. Avoid writing these for the network block
-parameters. This is a generic filter that cover cases that may not have
-been explicitly addressed with a more specific commit to avoid control
-characters in the psk parameter.
